which will be substantially waterproof.

Another object is to provide'a simple and practical process formanufacturing ma terial of the above character.

A further object is to provide an inexpensive process for makingwaterproof fabric which may also have any desired color or design.

Other objects will be in part obvious and in part hereinafter pointedout.

The invention accordingly consists in the several steps and in therelation of either or one or more of those steps to each of the othersthereof, as well as to the material produced by such steps, as will beexemplified in the'hereinafter disclosed process andthe scope of theapplication of which will be indicated by the. claims that follow.

In brief, the process may be said to consist of taking coarse raw cottonand treating the same toremove the natural oils and fats thereof, afterwhich the cotton is treated and formed into sheets of the desired sizeand rendered Waterproof by the addition or application of suitablematerials. The mat thus formed ma then be subjected to pressure and heatan have in corporated therewith coloring matter either throughout itsentire area or in predetermined portions to make a suitable design.

In carrying out this process briefly outlined above, we prefer to firstsubject the coarse raw cotton to the action of a gasolene mixture whichis found to be a suitable and inexpensive solvent for eradicating theSpecification of Letters Patent.

treated is then run through a picker and formed into sheets of desired.size, after: which the mat so formed may be bleached if desired,although this step is not in any way essential, especially if the mat isto be subsequently colored. These sheets are then treated with asolution composed largely of collodion or the like and rosin, to whichmay be added rubber cement. The mats are thoroughly saturated with thissolution and then dried, and pressed into thin sheets by being runthrough rollers under great pressure, and preferably at a relativelyhigh temperature. Any, form of roller may, of course, be used; but it isfound that large electrically heated collars are more desirable. Thefabric so manufactured may be dyed either before or after this pressingstep by the addition of coloring pigments placed over its entire area,or in predetermined spots to produce a regular design thereon.

The article so manufactured will be found to be strong, durable andinexpensive and capable of all uses where a coarse, strong woven fabricis now used.

As many changes could be made in carrying out the above process withoutdeparting from the scope of the invention, it is in tended that allmatter contained in the above description shall be interpreted asillustrative and not in a limiting sense.

-Having thus described our invention what we claim as new and desire tosecure by Letters Patent-ilk 1. The herein described article ofmanufacture composed of raw cotton impregnated with a solution ofcollodion, rosin and rubber.

2. The herein described article of manufacture composed of raw cotton,collodion and rosin pressed together in thin flexible sheetsp I 3.
